Description
Technical field
The present invention relates to a kind of coating and preparation method thereof, particularly to a kind of high definition projection wall covering and preparation method thereof.
Background technology
Projection screen application in life is very extensive, and it is mainly used in large conference room, command and control center, training
The occasions such as educational structure, meeting room, exhibition room, exhibition center, airport, show window.As the requisite partner of scialyscope, buy
Projection screen is also required to spend a high expense, and is also required to oneself as scialyscope and installs.Application was most in the past
Home projector curtain mainly has: picture frame screen, manual curtain and electric screen, but not only need separately installed, maintenance cost is higher, and
And also space limits, become projection system and enter the major obstacle of average family, and the appearance projecting paint well solves this
One problem.
Projection paint is a kind of cold coating product being mixed with filler and various additive, it is not necessary to special instrument and skill, can
So that smooth the surface conversion of japanning high performance projection screen can be become by any.But, the projection screen of a lot of curtain wall forms in reality
Curtain is not inside the projection room and movie theatre of specialty, and is under natural light environment appreciating for people more, and projection screen is respectively
Planting under light environment, the most in bright ambient light under environment, its surface is projected by high light, it is easy to cause imaging to be drawn
Face is unintelligible, uneven, dazzle, white haze shape are serious.If it is known that projection screen imaging picture white haze shape is serious,
Can be substantially reduced contrast and the brightness of picture, thus it is unclear to easily lead to user viewing, so lose itself displaying,
Demonstration or effect of advertising.Therefore, solving the ambient light impact on imaging picture, design one is effective against ambient light to imaging
The scheme of the projection screen paint of the interference of picture either still improves viewing comfortableness and is all for reducing the cost of projection screen
Extremely it is necessary.
Number of patent application be 201520313487.9 Chinese patent provide a kind of can strong light environment use Novel Microstructure throw
The design of shadow screen, including the base material of absorbable light, is interval with several for absorbing light to reduce on base material
The raised line that imaging is disturbed by ambient light, raised line is horizontally set, and is parallel to each other, on the substrate surface between raised line and raised line
Being provided with the projection imaging layer for projection imaging, the surface of projection imaging layer, less than the outer surface of raised line, is made so that play interference
The raised line that can be made up of light absorbent of ambient light absorb and block, and then can effectively reduce ambient light to imaging picture
Impact, makes that imaging picture is apparent, contrast is higher, brightness is higher.Improve the imaging picture of existing projection screen, and its
Processing technology is simple, it is easy to implement.
Number of patent application is a kind of high projection system to comparison of United States Patent (USP) of US6529322B1, by optical selective glass
Filter layer, AR backing layer and the appropriate design of surface layer so that the light of projector is neutralized by the collection of selectivity and reflects, and natural light
Line then is projected by the absorption of selectivity, improves contrast, decreases the ambient light impact on viewing effect.
Although existing reduction ambient light can solve problem to a certain extent to the design of the impact of imaging picture, but logical
Crossing the scheme of the screen construction designed selective absorbing and reflection to realize available light and projection ray, screen construction is more multiple
Miscellaneous, naturally also cause the defect that projection screen is relatively costly.
Summary of the invention
It is desirable to provide a kind of high definition projection wall covering, by selectivity synthesis acrylic acid modified polyurethane resin system
Electronic structure and quantity, and the structure of the internal filler particles of resin system and nano effect, realize the screen selection to light
Property absorb and reflection function, and then reduce the natural environment interference to viewing effect, improve viewing comfortableness.
A kind of high definition projection wall covering and preparation method thereof, the viscosity of coating is 7000～9000mPa s, it is characterised in that be coated with
